摘要： A feeding arrangement for feeding comminuted material to a treatment stage using a plug screw feeder. The invention relates to a design of the inlet to the plug screw feeder wherein, at least 2 chutes (20a,20b) are arranged to feed material to the feed screw (10), and that the cross section of each chute is arranged such that more than 50% of the outlet cross section of a first chute (20a) is located on one side of the feed screw axis (CC) and more than 50% of the outlet cross section of a second chute (20b) is located on the other side of the feed screw axis. In an upgrade version for existing plug screw feeders with large rectangular inlets is an insert body (11a) used filling the rectangular inlet, besides the chutes (20a, 20b) passing through the insert body (11a).

摘要： The present invention relates to systems and methods for mixing various components of asphalt concrete in a mixer and then dispensing the asphalt concrete from the mixer. While the mixer can include any suitable component, in some instances, it includes a heated container, a mixing mechanism that is configured to mix asphalt and an aggregate to form the asphalt concrete within the heated container, and an auger that is configured to force the asphalt concrete out from the heated container. In some cases, a portion of the auger is disposed in a heated cover. In some cases, the cover further comprises a gate that is configured to open (and close) to allow the asphalt concrete to flow from (and be retained in) the heated container. Other implementations are also described.

摘要： An automated granule portioning system includes at least one volumetric measuring chamber capable of adjusting the volume of the chamber automatically to a programmed target volume and arranged to receive a first portion of granules into the chamber to fill the target volume. A transport system automatically delivers the target volume of granules from the chamber to a weighing device. A granule metering device dispenses granules and, depending on a signal from the weighing device that the first portion of granules is below a programmed target weight, dispenses granules to the first portion to increase the weight to achieve a second portion having the target weight.

摘要： An integrated granular-material scoop and near-vertical lifting feeder/conveyor includes special connections and skirts between a bullnose rotating scoop and an open-helical screw that provides the rotations and material lift and evacuation. A conical working-face of the bullnose rotating scoop has symmetrically distributed graters and vents to break loose and force-in granular material from natural deposits and cargo holds. The bullnose rotating scoop and the open-helical screw its attached to move the material into a continuous layer on the inside surface of an outer stationary sheathing. A motor drive attached to the open-helical screw above at the delivery end provides the lifting force necessary.
